BT saw a significant rise in its number of broadband subscribers between October and December 2016.
According to the company's latest trading statement, its broadband base grew by 83,000 throughout the quarter to reach 9.27 million.
This is higher than the 76,000 increase it saw in the previous three-month period.
BT's trading statement also revealed that more than seven million customers now take a fibre-to-the-cabinet or fibre-to-the-premises-based broadband service via their UK network.
Furthermore, the company's infrastructure subsidiary Openreach reported that the number of missed appointments has come down by half in the last year.
These developments helped BT's quarterly revenues rise from £6 million in Q3 to more than £6.1 million in Q4, although its reported profits before tax dropped slightly from £671 million to £526 million.
Gavin Patterson, Chief Executive of BT, commented: "We face a more challenging outlook in the UK public sector and international corporate markets, but we’ve seen record growth at EE, strong momentum in Consumer and our highest ever fibre net connections in Openreach."
He insisted that customer experience is a top priority for BT, which is why EE is now answering all of its customers' calls in the UK and Ireland, and Openreach has worked to reduce the number of missed appointments.
"We’ll continue to invest to ensure our service levels improve and that our customers see the benefit," Mr Patterson said.
He went on to stress that BT is "pushing ahead" with reforms at Openreach, particularly in areas such as governance and customer service.
Telecoms regulator Ofcom recently ordered BT to legally separate from Openreach, so it is run as a distinct and legally separate company with its own board.
Mr Patterson said BT continues to believe that an agreement can be reached with the watchdog regarding its Digital Communications Review.
"We think these changes address Ofcom’s concerns and can form the basis for a fair, proportionate and sustainable settlement," he added.
